Under RHEL4, I've mounted a drive (/dev/sdb1) under /home and it mounts with no problem a boot time since I have an entry in /etc/fstab. Using the same parameters under RHEL5, /home is a 'read only' directory. I've tried to add a 'rw' option to /etc/fstab, but /home remains a 'read only' file system.
